借助弹簧结构参数以及结构设计创新，提出了一种替代单向螺旋弹性滚子的新型反旋对接弹性滚子。通过ABAQUS建立了普通圆柱滚子、单向螺旋弹性滚子及反旋对接弹性滚子的有限元分析模型，对比分析了它们的质心轴向位移及反旋对接弹性滚子对接面的应力分布情况。研究表明这种新型反旋对接弹性滚子能继承单向螺旋弹性滚子的主要优点，且能避免单旋向螺旋弹性滚子在运动中的轴向偏移及因此与内外圈挡边接触产生较大的磨损。

This paper presents a new anti-spin thread connection elastic roller(ASTCER)that substitutes unidi-rectional helical elastic roller through structural design innovation with spring structure parameters. The finite element analysis model of ordinary cylindrical rollers,unidirectional spiral elastic rollers and anti-spin thread connection elastic rollers is established based on the ABAQUS. The axial displacement of their center of mass and the stress distribution of anti-spin thread connection elastic rollers are analyzed through their stress compari-son. Theoretical studies show that the new anti-spin thread connection elastic roller inherits some advantages of the unidirectional spiral elastic rollers and can avoid the axial offset of the single spiral elastic roller in motion and the huge wear in contact with the inner and outer rings.
